(54) CONNECTOR AND CONNECTOR ASSEMBLY


(57) A connector (100) comprises: an insulating housing (110), and a single conductive terminal (120) contained in the insulating housing. The conductive terminal comprises: a pair of elastic clamping sheets (123a, 123b) adapted to grip a conductor of a wire (10) inserted into the connector, and a releasing mechanism (124, 124a) adapted to separate the pair of elastic clamping sheets in directions away from each other, to release the clamped conductor. Since the conductive terminal comprises the wire releasing mechanism, the conductor of the wire may be plugged in and pulled out of the connector repeatedly, thus the wire may be replaced conveniently. Additionally, since identical connectors are connected to each other, forming a connector assembly with different numbers of conductive terminals, only one mold is required to manufacture housing of each connector, thereby the manufacturing cost is reduced.
